Argynnis Laura. 



Male. — Expands 2.2 inch. 



Upper side deep red-fulvous, obscured at base of primaries and still 

 more at base of secondaries, the ground there being black with a slight 

 dusting of fulvous ; the black markings as in the allied species, rather 

 heavy, while the nervules of primaries, especially the discoidal, and the 

 branches of median, — and on secondaries the branches of sub-costal, are 

 widely bordered with black ; the mesial band of secondaries confluent • 

 fringes yellow-buff, black at the ends of the nervules. Under side of 

 primaries red-orange at base and along the median nervules ; also within 

 the P-shaped spots of cell : remainder of wing, which includes the outer 

 half of cell, and area to apex and hind margin, yellow-buff; the upper 

 marginal lunules more or less silvered, as well as the sub-apical spots ; 

 secondaries pale yellow ; the belt between the outer rows of spots broad, 

 clear colored, the spots large and well-silvered ; the basal and discal areas 

 mottled with delicate ferruginous ; in one example, brown, in some lights 

 a little greenish ; the marginal spots broad, rounded, edged with a few 

 black scales ; the spots of second row broad ovals, except fourth from 

 costa, which is minute, and the seventh on margin, irregularly lunate • all 

 bordered with black anteriorly ; the third row consists of either four or 

 five spots, the third and fifth sometimes one or both obsolete ; the first on 

 costa rounded, the second large, sub-triangular, and fourth sub-lunate ; 

 all edged above with black ; in cell a rounded spot, a long oval in sub- 

 median interspace, both edged with black ; patches of silver at the top 

 of the interspaces at base ; shoulder and abdominal margin well silvered. 



Female. — Expands 2.35 inches. 



Upper side paler over discal area ; the margins edged broadly with 

 black ; under side very nearly as in male.
